ONE adventurous Tasmanian couple yesterday took a giant leap into their married life.

Jarrod Wells and his new wife Cassy (nee Austin), of Police Point, near Dover, became the first to say I do at the top of a seven-metre-high waterfall, Freestyle Falls, in Dove Canyon.

Last year the couple entered a video in the Cradle Mountain Canyons' dream wedding competition and won.

The prize included abseiling and canyoning through the World Heritage Area for them and 10 friends or family.

The pair were married by Anthony O'Hern, an authorised celebrant who is also co-owner of Cradle Mountain Canyons.

To mark the end of the ceremony, the newlyweds kissed, held hands and jumped into the water. Their friends, family and tour staff were an audience in the pool below.

The style of wedding might not be everyone's cup of tea, but the couple agree that it was perfect for them.

Mr Wells, formerly of Ulverstone, said that not even a 150-metre fall while bushwalking with his brother at Leven Canyon in 2003, or the fact that Mrs Wells last year underwent surgery on her back requiring a long recovery and time off work, could curb their enthusiasm when choosing a canyon wedding.

"It was 23 degrees and sunshine, no breeze and a few clouds floating on the horizon: the weather was perfect and everything went amazingly well,'' Mr Wells said.

Mrs Wells said: "It is one of the most amazing and unique experiences, and to do it with our 10 friends is a memory that definitely won't be forgotten.''

Back on higher ground, the wedding party were joined by the happy couple's parents and close family members, including Mr Wells's daughter Lucy, 6.
